Definitions

  • the present invention relates to an improved lighting device for a structure and/or installation in which illumination is required and/or provided, preferably for a roofing installation, in particular for a pergola or curtain, but also for a piece of furniture or a furnishing complement.
  • strips of lights preferably strips of LED lights (also called “led strips")
  • strips of lights preferably strips of LED lights (also called “led strips")
  • the LED strips can be applied to the articulated arms and/or to the rigid beam which is moved and/or to the support structure of the curtain, while in the sliding curtains the LED strips are applied to the guides and/or uprights supporting the guides and/or other parts of the tent support structure.
  • extruded section bars of polymeric material inside which the LED diodes are embedded, have already been proposed on the market.
  • the extruded sections are then hermetically closed at their ends.
  • the extruded section thus obtained which is closed at its ends, is available on the market with predefined dimensions and, therefore, at the time of its installation it is difficult to customize according to the particular characteristics of the roofing installation, such as for example those defined by the length of the component of the cover to which the section bar - with the LED strips inside - must be applied.
  • this type of extruded section with the LED diodes inside cannot be tailor cut according to the specific installation requirements since, otherwise, it would then be open at at least one of its ends and, therefore, the LED diodes would be exposed to solid particles and liquids from the external environment.
  • US 2012/0182755 presents a solution in which a LED strip is coupled with optics which allow a uniform diffusion of the light produced by the LED diodes of the strip itself, thus avoiding the formation of luminous "spots".
  • the LEDs and the optics are wrapped by covering films, which however do not by themselves define a suitable protection from the internal environment. Therefore, the LED strip diodes and the optics, partially wrapped by said covering films, are inserted inside a section bar which has the function of protecting them from dust and atmospheric agents. Furthermore, in order to obtain effective protection of the LEDs from the external environment, the section bar is closed at both ends by a pair of plugs.
  • WO 2005/106320 presents a solution in which a LED strip is positioned inside a section bar, which is subsequently closed, and filled with a filling material (for example silicone) to cover and protect the LED diodes.
  • a filling material for example silicone
  • US 2011/0007514 presents a solution in which a LED strip is inserted inside a section bar, which is subsequently sealed at the ends by plugs to allow insulation of the LED strip to be obtained inside the section bar itself.
  • This solution is not completely satisfactory since the plugs are particularly complicated to manufacture, thus making this solution particularly expensive; in particular, these plugs must be configured to allow ventilation inside the section, and at the same time they must keep the dust, humidity and atmospheric agents outside, as well as being able to engage by interlocking with the ends of the section.
  • Object of the invention is to propose a perfected lighting device to be installed on a component of an installation and/or a structure, preferably for a cover installation, which eliminates all the drawbacks found in the known solutions.
  • Another object of the invention is to propose a lighting device that is simple, easy and quick to install, even by unskilled personnel.
  • Another object of the invention is to propose a device that allows to have a uniform light substantially along its entire length.
  • Another object of the invention is to propose a device that is easily customizable and adaptable, even when in operation or during the installation.
  • Another object of the invention is to propose a device in which the lighting sources are always protected from the external environment.
  • Another object of the invention is to propose a device which is both improved and/or alternative to the traditional ones.
  • Another object of the invention is to provide a device that has an alternative characterization, both in constructive and functional terms, with respect to the traditional ones.
  • Another object of the invention is to propose a device that can be obtained in a simple, rapid manner and with low costs.
  • Another object of the invention is to provide a device that can be produced in series and in a quick and efficient manner.
  • Another object of the invention is to provide a device which allows to obtain lighting that are as a whole and aesthetically pleasing and that provides the viewer the sensation of being in front of a solution of high quality, both on the aesthetic and functional level.
  • Another object of the invention is to provide a device that is of high standards, both functional and constructive, and at the same time of accessible cost, thus allowing the possibility of its widespread distribution.
  • Another object of the invention is to propose a covering installation which is provided with a lighting device which provides a uniform and pleasant light, and which can be obtained and installed in a simple, rapid manner and with low costs.

  • these two or more portions of the section bar 30 are obtained by using two or more different materials that are extruded together during the construction of the profile itself.
  • an electric cable 60 is associated with the LED strip 40 - preferably at one of its end portion - for connection to a power supply source, not shown, such as for example a battery or the mains.
  • the cables 60 connected to the LED strip 40 of the lighting devices 18 are electrically conductive connecting cables inside the components of the covering installation and, therefore, are hidden from view from the outside.
  • the LED strip 40 of device or lighting 18 is also connected to a control device (not shown).
  • the control device is of the type described in the Italian patent application 102017000090501 .

  • processor is configured also to allow the wireless connection (preferably radio, via infrared, wi-fi...) with an external device (such as a remote control) to command the activation/deactivation of the LEDs 41, and the variation in brightness generated by these.
  • the lighting device described here differs from US 2012/0182755 , WO 2005/106320 and US 2011/0007514 in that the LED strip comprises a protective casing/covering - inside which the LED diodes are provided - such as to make the strip itself, already on its own, protected against the penetration of dust and against any penetration of liquid substances.
  • the LED strip comprises a protective casing/covering - inside which the LED diodes are provided - such as to make the strip itself, already on its own, protected against the penetration of dust and against any penetration of liquid substances.
  • This is particularly advantageous in that, while allowing the LED strip to be removed from the section bar for its replacement, it causes the strip itself to be partially housed outside the containment section, as well as allowing an open section to be provided which is not sealed at the ends (i.e. without caps, lids or other closing end elements), thus simplifying both the production of the section bar and the installation/removal of the strip in/from said section bar.
